Allium hybrid plant named ‘Windy City’

ABSTRACT

A new, distinct  Allium  hybrid plant as shown and described, characterized by dark green foliage in combination with purple-violet flowers, on semi-sterile plants.

Latin name: Allium hybrid.

Cultivar name: ‘Windy City’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct hybrid of Allium hybrid plant named ‘Windy City’ characterized by dark green foliage in combination with purple-violet flowers, on semi-sterile plants. The new Allium hybrid was the result of a breeding program taking place in Hebron, Ill. since 2010. ‘Windy City’ arose as a selection from seed sown from open pollination of unnamed plants of Allium. The exact parentage of Allium hybrid ‘Windy City’ is unknown, however the female or seed parent is believed to be Allium hybrid ‘Summer Beauty’, while the male pollen parent is unknown. The selection of the new plant was due to its' dark green foliage in combination with purple-violet flowers, on semi-sterile plants. Asexual division propagation has been the means of reproduction. The initial cutting and division propagation has taken place at a nursery in Hebron, Ill. in 2011. The new Allium has shown to be stable and identical in reproduction to the parent after dividing over 5000 plants from 2011 to 2015.

SUMMARY OF THE INVENTION

The new Allium hybrid plant named ‘Windy City’ characterized by dark green foliage in combination with purple-violet flowers, on semi-sterile plants, have been observed to be unique and stable.

Plants of the new Allium hybrid plant named ‘Windy City’ can be compared to the likely female or seed parent, Allium hybrid ‘Summer Beauty’, not patented. 1. The new plant height is typically 40-45 cm tall while Allium hybrid ‘Summer Beauty’ is typically 60 cm tall. 2. The new plant also has thinner dark green foliage RHS color 137 A measuring 10 mm wide, while Allium hybrid ‘Summer Beauty’, has green foliage RHS 137 C measuring 15 mm wide. 3. The new plant also has darker flowers RHS color N 81 A, while Allium ‘Summer Beauty’, has lighter pink flowers, RHS color not measured.

Plants of the new Allium hybrid can also be compared to plants of Allium hybrid ‘Millenium’, not patented. 1. The new plant height is typically 40-45 cm tall while Allium hybrid ‘Millenium’ is typically 50 cm tall. 2. The new plant also has thinner dark green foliage measuring 10 mm while Allium hybrid ‘Millenium’, has wider green foliage measuring 15 mm wide. 3. The new plant also is mostly sterile with very little seed set after flowering, while Allium hybrid ‘Millenium’, is fertile with heavy seed set after flowering.
